You can reuse components in a design by either creating a copy that remains linked to the original, or that diverges from it. You can also reference external designs as components in the current design.
There are three commands to help you reuse components: Paste, Paste New, and Insert into Current Design.
Use Paste to create an identical copy of a component. All copies maintain a linked association with each other. When you change one copy, all of the copies created using Paste update to reflect the same changes.
The new copy of the component displays in the browser and in the canvas.
:1 and :2 at the end.Use Paste New to create an independent copy of a component. Each copy is unique. When you change one copy, none of the copies created using Paste New will update to reflect the changes.
The new copy of the component displays in the browser and in the canvas. You can position each copy independently within the assembly.
The outcomes of Paste New depend on whether or not you’re working in a collaborative editing hub.
If you're working in a hub with collaborative editing, skip to this section. Check for this icon
next to the hub name to confirm collaborative editing is available. Learn about collaborative editing.
In a non-collaborative editing hub, the pasted component keeps the part number, part name, and properties of the original component that was copied. This applies to children of the component, if they exist.
There is one exception to this. If a pasted component has the same name as a component that’s already in the target design, the pasted name is incremented with a number; for example, if you paste Component1 into a design that already contains a component named Component1, the pasted component name becomes Component2. The part number is also incremented.

Box 1 assembly, Component1 is copied.Component2 is a child of Component1, it’s automatically copied, too.Box 2 assembly also contains a component named Component1.Box 2 assembly, Component1, which was copied from the Box 1 assembly, is pasted using Paste New. It becomes Component2 because there is already a Component1 in this assembly.Component2, is incremented to Component3.The same thing happens even if Component1 was once in the Box 2 assembly but was deleted at some point.

Box 1 assembly, Component1 is copied.Component1, but it was deleted at some point and does not appear in the browser. Fusion still considers this Component1 to be part of its design history.Box 2 assembly, Component1 is pasted using Paste New and becomes Component2 so as not to conflict with the historical Component1. When you paste as new in a collaborative editing hub, the component is given a new, unique part number. If it has child components, those retain their part numbers. All other properties are maintained.

Top Lid Assembly is copied.Top Lid Assembly is part of a shared part number group.Top lid assy.Top Lid Assembly is pasted as new into a new assembly. Since collaborative editing hubs support shared part numbers, there are various outcomes possible when you paste as new:
| Component copied | Part of Shared Part Number Group? | Part Number after paste | Name after paste | Other properties after paste | Shared Part Number status of the copy |
|---|---|---|---|---|---|
| Individual component, with or without children | No | Unique new | Retained | Retained | Remains an individual component not part of a shared part number group. |
| Child of copied parent | No | Retained | Retained | Retained | Becomes a secondary model in a new shared part number group. The original component that was copied becomes the primary model in the group. |
| Individual component, with or without children | Yes | Unique new | Retained | Retained | Remains an individual component, no longer part of a shared part number group. |
| Child of copied parent | Yes | Retained | Retained | Retained, always determined by the primary member of the shared part number group | Becomes a new secondary model in the existing shared part number group. |
Use the Insert into Current Design command to reference an external Fusion design as an External Component (xref) within the assembly of the current design. The original design remains outside the current design, but you can use Edit In Place
to edit it directly as a component in the context of the assembly of the current design. When you change the original design, either from within the current design or by opening and editing it directly, the changes are reflected everywhere the design is referenced.
The inserted design displays in the browser as a component in the assembly and in the canvas.
